The QNCTK3-16 Split Core Current Transformer is a precision open-type clamp CT sensor designed for accurate and reliable AC current monitoring. Its split core design allows for easy installation directly onto existing wiring without any interruption to the circuit, making it ideal for retrofitting into electrical panels and monitoring systems. This versatile sensor supports a wide AC input range from 5A up to 100A and delivers a clean, standardized DC output voltage — available in 1V, 3.3V, 4V, or 5V configurations — for seamless integration with data acquisition systems and microcontrollers. With an impressive accuracy rating of 0.5% and a broad operating frequency range of 50Hz to 200KHz, it performs reliably across a variety of waveforms and applications. The unit also features a compressive strength of 3kV/50Hz/1min and weighs approximately 3.2 oz. Color-coded output leads (Black: 0V, Red: 5V) simplify wiring connections. Whether used in industrial monitoring, energy management, or DIY electronics projects, this current transformer delivers consistent, precise performance.
